On my return flight to the US of A, I made a stop in NYC. I went via Newark airport. From previous experience I knew that the rail line into Manhattan was a convenient one. But had I not known that from before, I would have ended up seeing buses as my only option. At the exit of Newark International, where you see the sign for 'Ground Transportation' the arrow points to the right - THE EXACT OPPOSITE DIRECTION of the rail line station to Manhattan which has no sign at that juncture. The bus ride costs $5 more than the train and is far less comfortable. Does NJTransit know people get funneled into the bus services like that?
[Update: Looking at the generic comments that this post collected, there is obviously money to be made by hiding the comfort of NJ Transit's smooth rail ride straight into Penn Station and duping people into paying more for a bumpy bus ride.]
